The microscopic surface morphologies were observed by field emission scanning electron microscopy (FESEM, JSM-5610, JEOL, Japan) equipped with energy dispersive spectroscopic (EDS), operating at 3 kV acceleration voltage. A Fourier-transform infrared (FTIR) spectrometer (FTIR, Nicolet IS50, Thermo, USA) equipped with an ATR accessory was used to examine the chemical groups of the sample. All spectra were recorded in the range from 4000 to 450 cm−1 with 4 cm−1 resolution. X-ray photoelectron spectroscopy (XPS, K-Alpha Thermo, USA) data was obtained using an electronic spectrometer. The crystal phase of the samples was tested with an X-ray diffractometer (XRD, D8, Bruker, Germany). The quantitative test of TiO2 was quantified through atomic absorption spectrometry (AAS, Sollar M6, Thermo, USA) with air-acetylene flame. Separate hollow cathode lamps radiating at wavelengths of 248.3 (Ti) were used to determine the amount of Ti. The mechanical strength of the samples was tested through a universal testing machine (Instron 5943, USA) according to the GB/T18318-2011 standard. The optical properties of the samples were studied with a UV-vis spectrophotometer (Hitachi U-2900, Japan) in the wavelength range of 200–800 nm.

The chemical structures of CNFs, AN-CNFs and CoTCPcNa-AN-CNFs were analyzed with X-ray photoelectron spectroscopy (XPS) measurements (Kratos AXIS Ultra DLD). The standard Mg Kα (1256.6 eV) X-ray source operated at 10 mA and 15 kV. All binding energies were referenced to Au (4f7/2) at 84 eV. The thermal stability of CNF, AN-CNF and CoTCPcNa-AN-CNFs was investigated using Mettler-Toledo TGA under a nitrogen atmosphere at a flow rate of 100 mL·min−1, with a heating rate of 20 °C·min−1. The cobalt content in CoTCPcNa-AN-CNFs was measured by atomic absorption spectrometry (Thermo Sollar M6), allowing calculation of the content of CoTCPcNa in CoTCPcNa-AN-CNFs. The mass content of CoTCPcNa in CoTCPcNa-AN-CNFs is 2.67% (m/m). The morphology of CNFs, AN-CNFs and CoTCPcNa-AN-CNFs were carried out by transmission electron microscope using JEM-2010. Nitrogen adsorption-desorption isotherms were carried out at 77 K using a Micromeritics ASAP 2020 analyzer. Before adsorption, the samples were out-gassed at 323 K for 10 h. Fourier transform infrared spectroscopy (FTIR) spectra of a sample in KBr pellet were recorded on a Nicolet Avatar 370 spectrometer.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
